Learn how to improve API performance using ASP.NET Core caching mechanisms, including in-memory, Redis, and response caching

intermediate Published 4 Mar 2026

Action Steps

Implement in-memory caching using the IMemoryCache interface to store frequently accessed data
Configure Redis caching to distribute cache across multiple servers
Use response caching to cache HTTP responses and reduce the number of requests to the API
Test and compare the performance of different caching mechanisms to determine the best approach
Apply caching strategies to specific API endpoints to optimize performance

Who Needs to Know This

Backend developers and architects can benefit from this knowledge to optimize their API performance and reduce latency

Key Insight

💡 Caching can significantly improve API performance by reducing the number of requests and latency
